Its latest big release, Quentin Tarantino's Inglourious Basterds, has raked in close to $230m (£142m) at the worldwide box office so far. But the Weinstein Company, the production and distribution studio headed by brothers Harvey and Bob, is continuing to axe staff, the New York Post reports.

Another three dozen posts are to be cut in the next month to bring the headcount down to 90, following several waves of redundancies that began last October. When the brothers founded the company in 2005 after selling Miramax to Disney, their staff numbered around 160. Soon it will be almost half that.

The firm is also planning to reduce its number of releases to 10 a year – four for each brother, plus two others they plan to pick up at festivals. "In this economic climate, it makes sense to focus on a smaller slate," said a company representative, "and with that, we need fewer people. By the end of the year, the look of the company will be complete, and we can continue releasing successful films."

In June, the Weinstein Company hired financial advisers Miller Buckfire to help it restructure and delayed the release of two titles: the John Cusack and Gong Li-starring period thriller Shanghai and the romantic mystery All Good Things, directed by Andrew Jarecki of Capturing the Friedmans fame.

Other high-profile Weinstein releases this autumn include The Road, John Hillcoat's adaptation of Cormac McCarthy's postapocalyptic novel, whose US release date has been moved from October to the end of November, and Nine, the musical starring Daniel Day-Lewis and directed by Rob (Chicago) Marshall, which is released around the same time.

Inglourious Basterds was the biggest opening ever for the Weinsteins' prodigal son, Quentin Tarantino, though profits will be shared 50-50 with co-distributor Universal.
